Airport security officers in Pakistan arrested a Greek man Sunday on accusations he tried to smuggle a handgun hidden in a laptop computer onto a plane.

Airport security official Col. Jamshed Hayat Niazi said the man, identified as Annkhus Sarzio, was arrested at the Karachi airport as he tried to board a flight to Dubai, where he was to catch another plane to Athens.

Officials screening Sarzio's luggage at an airport security scanner discovered a 9 mm pistol concealed in his laptop's battery compartment, Niazi said. Police were interrogating Sarzio, and it was not immediately clear if the gun was meant to be part of a hijacking attempt, he said.

Sarzio's mother was also traveling with him, but she was not detained, he said.
